Definitions

  • the invention relates to a soil cultivation device, in particular for the care of soil surfaces between crops, according to the preamble of claim 1.
  • Such a harrow is from the DE 201 15 048 known.
  • This has a plurality on a support frame pivotally arranged harrow tines, which are biased by a respective spring.
  • the springs are connected on the one hand to the respective harrow tines and on the other hand via a pull cable with a control element arranged on the support element.
  • On the adjusting element five different mounting options for the tension cables connected to the springs are provided, so that the bias of the springs and thus the bias of the harrow tines can be adjusted centrally by changing the position of the attachment points of the traction ropes.
  • a disadvantage of this tillage device with manual adjustment of the bias is that the processing must be interrupted for adjustment.
  • the soil condition can constantly change during tillage and the machining process must be stopped before each adjustment, a change in the bias of the harrow tines is associated with a considerable amount of time.
  • the object of the invention is to provide a harrow of the type mentioned, which allows a quick and easy change in the bias of the harrow tines even during tillage.
  • the adjusting device is associated with an electric or hydraulic actuator that can be controlled by means of a control device.
  • the central change in the bias of the harrow tines or the setting of the tine pressure can thus, for example, from the towing vehicle also during processing respectively. If necessary, the tine pressure can be easily and quickly adapted to the respective soil conditions, for which purpose the machining process does not have to be interrupted.
  • the farmer can, for example, specify the desired tine pressure on the electronic control unit, which can then also be displayed and monitored via a corresponding display device.
  • An electric actuator may conveniently comprise a geared motor mounted on the support frame, e.g. is coupled via a belt or chain drive with at least one thumbwheel for rotation of at least one connected to the springs via pull cables drive shaft.
  • a with respect to the energy supply particularly advantageous and therefore for driving large tillage equipment with many harrow tines perfectly suitable hydraulic drive may comprise a arranged on the support frame hydraulic cylinder which is coupled via a Switzerlandstoffan für lovatose cylinder which is coupled via a Switzerlandstoffan für lovatose cylinder and at least one thumbwheel for rotation of at least one connected to the springs via pull cables drive shaft ,
  • the tillage implement shown in a side view is a so-called tine harrow, which is used in agricultural agriculture for soil cultivation. and Seeds cultivation of crops, especially for weed control in organic crops, is used. It contains several arranged on a support frame 1 harrow tines 2, which are biased by a respective spring 3 against a stop 4.
  • the support frame 1 has at its in FIG. 1 right end to a three-point block 5, via which the support frame 1 can be attached to a towing vehicle.
  • the support frame 1 includes a plurality of spaced-apart longitudinal members 6 and cross struts 8, on which the angled at the bottom in the direction of harrow harrow tines 2 are articulated in the longitudinal and transverse directions spaced from each other.
  • one end of the springs 3 is attached to the harrow tine 2 below its articulation, while the other end of the springs 3 is connected via a respective traction cable 7 with a rotatably mounted on the support frame 1 adjusting shaft 9.
  • a central adjustment of the tine pressure of the harrow tines 2 can be achieved.
  • the control of the geared motor 13 via a mounted in towing vehicle control unit 14 which is provided with a monitor or other electronic display device 15.
  • an initiator or sensor 16 is arranged, by means of which the angular position of the setting wheel 10 can be detected by means of several evenly distributed on the drive wheel over its circumference holes 17 and a reference zero point 18. Thereby, the selected bias can be determined and displayed on the electronic display device 15 of the controller 14.
  • FIG. 2 is a part of another tine harrow with a hydraulic actuator shown schematically.
  • the articulated to the cross struts 8 harrow tines 2 are biased by a spring 3 against a stop 4.
  • the one end of the spring 3 is also fixed to the harrow tines 2, while the other end of the spring 3 is connected via a pull cable 7 with an adjusting shaft 9 rotatably mounted on the support frame 1.
  • a thumbwheel 10 is provided, which is here, however, coupled via a designed as a cable Ceizieranssen with the piston 19 of a hydraulic cylinder 20.
  • the Switzerlandstoffanssen includes a guided over pulleys 21 rope 22, whose one end to the piston 19 of the hydraulic cylinder 20 and the other end with the adjusting wheel 10 is connected. By displacement of the piston 19 so the thumbwheel 10 is rotated and thus the bias of the harrow tines 2 are changed.
  • the actuation of the hydraulic cylinder 20 via a designed as a 2/2-way valve hydraulic control valve 23 which is arranged on the support frame 1 and via a supply or return line 24 and 25 with a supply unit on the towing vehicle can be connected.
  • a connecting line 26 to the control unit 14 the control valve 23 can be controlled from the towing vehicle.
  • a linear measuring system 27 is further attached, which is connected via a line 28 to the control unit 14. With the help of the linear measuring system 27, the displacement of the piston 19 and thus the adjustment of the bias of the harrow tines 2 detected and displayed via the line 28 to the electronic display device 15 of the controller 14.
  • FIG. 3 shows in a plan view of a three-piece tine harrow, which is equipped with a hydraulic actuator described above.
  • the support frame 1 of this tine harrow consists of three composite lattice-like parts 1a, 1b and 1c, of which the middle part 1a contains the three-point block 5 provided for attachment to the towing vehicle.
  • the two outer parts 1b and 1c of the support frame 1 are hinged upwardly on the central part 1a.
  • the different parts 1a, 1b and 1c also have three separate adjustment shafts 9a, 9b and 9c with separate setting wheels 10a, 10b and 10c.
  • the adjusting wheels 10a, 10b and 10c are respectively to the in FIG. 3 attached to right ends of the adjusting shafts 9a, 9b and 9c.
  • the harrow tines are mounted laterally offset by 28 mm to each other.
  • springs 3 and corresponding traction cables 7, these are connected to the adjusting shafts 9a, 9b and 9c for simultaneous adjustment.
  • the piston rod 19 of the hydraulic cylinder 20 fastened to the middle part 1a of the support frame 1 is connected to the setting wheel 10a by a first cable 22a guided via first deflection rollers 21a. From the piston rod 19 also performs a second cable 22b via second pulleys 21b to the setting wheel 10b.
  • This Switzerlandstoffanssenanssen of several According to deflected ropes 22a to 22c so all arranged on the different parts 1a, 1b and 1c of the support frame 1 harrow tines 2 can be adjusted by the hydraulic cylinder 20 centrally.
  • additional turnbuckles 29a, 29b and 29c are arranged in the embodiment shown. Through this, if necessary, a fine adjustment of the different parts can be made.
  • FIG. 4 may be attached to the hydraulic cylinder 20 and a mechanical display device for displaying the selected biasing position.
  • a pointer 30 which cooperates with a fixed frame on the support frame 31.
  • this mechanical display device can be monitored by the hydraulic cylinder 20 preselected bias of harrow tines 2.
